Why students can pass your test and still not understand

One of the more uncomfortable things research reveals about learning is this: students can perform well on a test and still not understand what they have been taught.

They memorise procedures, follow patterns from worked examples, and reproduce answers accurately in familiar conditions. Then, weeks later or in a different context, the same content appears and they struggle as though they are encountering it for the first time.

This is the transfer problem. And it has significant implications for how we plan and assess.

Passing a test is not the same as understanding

Marton and Säljö (1976) identified two distinct approaches students take to learning. Surface approaches involve reproducing information to meet immediate demands. Deep approaches involve making sense of material and connecting it to existing knowledge.

Both can produce acceptable test results under the right conditions. But only deep approaches lead to durable understanding.

When assessments are highly predictable and closely mirror the practice students completed beforehand, performance may reflect familiarity rather than genuine understanding. Students learn to answer that question, not to understand the concept behind it.

The distinction matters because teaching is not preparation for a single task. It is preparation for ongoing thinking.

Transfer is the real measure of learning

Perkins and Salomon (1992) describe two kinds of transfer. Near transfer involves applying knowledge in contexts that closely resemble the original learning environment. Far transfer involves applying knowledge in genuinely new or unfamiliar situations.

Most school assessments test near transfer. Students answer questions that look like the questions they practised. When the same concept appears in a different format, a different subject, or a real-world situation, far transfer is required and this is where shallow understanding breaks down.

This is not a student problem. It is a design problem.

If assessments consistently test recall and reproduction, teachers may have limited visibility of whether students can actually use what they have learned.

What builds transferable knowledge

Research consistently shows that variability in practice strengthens transfer.

Rohrer and Taylor (2007) demonstrated that when students encounter problems in varied sequences rather than blocked repetition, retrieval becomes harder in the short term but more durable over time. Struggle during learning is often a sign that deep encoding is occurring.

Bjork (1994) on desirable difficulties reinforces this. Conditions that slow down immediate performance, such as spacing, interleaving, and varied contexts, tend to produce stronger long-term retention and transfer.

In practical terms, this means:

• Revisit concepts across different units, not just within the unit where they were introduced
• Use assessment tasks that place familiar knowledge in unfamiliar contexts
• Vary the format of questions so students cannot rely on pattern matching alone
• Connect concepts explicitly to other subjects or genuine real-world applications

The goal is not to make practice harder for its own sake. It is to build knowledge that holds under new conditions.

What to look for when reviewing assessments

Assessment tasks that test for genuine understanding tend to share certain features. They require students to apply, explain, or make decisions rather than recall or reproduce. They present information in a way that differs meaningfully from practice tasks. They ask students to justify their thinking, not just provide an answer.

When reviewing an upcoming assessment, it is worth asking:

• Could a student answer this correctly without understanding the underlying concept?
• Does the task require application or reproduction?
• Would a student who had only memorised a procedure succeed or struggle?
• Does the task reveal how students think, or only what they can recall?

Adjusting assessments does not always require starting from scratch. Small changes, such as presenting a familiar concept in a new context or asking for explanation alongside answers, can shift what the task actually measures.

Curriculum design and the transfer gap

Transfer does not happen automatically. It depends on how knowledge is built over time.

When curriculum is fragmented or when concepts are taught once and not revisited, students are less likely to develop the connections that enable transfer. When programs are coherent and designed to revisit and extend ideas across units, understanding deepens.

This is another reason why coherence across time matters so much. Coverage moves past an idea. Learning returns to it, extends it, and eventually connects it to something new.

The question is not whether students finished the unit. It is whether they can still use what they learned once the unit is over.

Planuva is designed to support the kind of curriculum visibility that makes this possible. When teachers can see how concepts are sequenced and revisited across units and year levels, they can plan deliberately for transfer rather than hoping it happens.
